About Marengo Therapeutics
Marengo Therapeutics, Inc. is a clinical-stage biotechnology company advancing innovative T cell-targeting therapies to revolutionize cancer treatment. The company's proprietary Selective T Cell Activation Repertoire (STAR™) platform is designed to selectively engage distinct T cell subsets by targeting the Vβ chain of the T cell receptor (TCR), empowering the immune system to combat cancer. To learn more, visit marengotx.com.

About the STAR™ Platform
Marengo's STAR™ platform is a multi-specific antibody-fusion technology derived from a proprietary library of antibodies targeting germline-encoded variable Vβ regions of the TCR. These antibodies are fused with T cell co-stimulatory moieties to promote durable anti-tumor immune responses.

About Invikafusp alfa (STAR0602)
Invikafusp alfa (STAR0602) is the lead candidate from Marengo's STAR™ platform. It is designed to selectively activate a common Vβ T cell subset found in all cancers by combining a non-clonal mode of TCR activation with a T cell co-stimulatory signal in a single molecule. This innovative approach promotes the expansion of clonally diverse, effector memory Vβ T cells, enhancing anti-tumor immunity and enabling durable tumor clearance. Extensive preclinical studies demonstrate STAR0602's potent anti-tumor activity in both mouse and human ex vivo models via a novel mechanism of action.

About the STARt-001 Clinical Study
STARt-001 is a Phase 1/2 clinical trial evaluating the safety, tolerability, and preliminary efficacy of invikafusp alfa as a monotherapy in biomarker-selected patients with advanced antigen-rich solid tumors, including PD-1 refractory and rare tumor types. The trial consists of two parts: Phase 1 dose escalation and Phase 2 dose expansion. For more information, visit clinicaltrials.gov (Identifier: NCT05592626).
